In Arabic, he is referred to as يونس (Yunus). The Book of Jonah is a short narrative that recounts the story of Jonah's divine mission to the city of Nineveh, his initial attempt to flee from God's command, and his subsequent journey inside the belly of a great fish. This story is significant in both Jewish and Christian traditions, as well as in Islam, where Jonah is considered a prophet. The narrative explores themes of divine mercy, repentance, and the universality of God's compassion. The story of Jonah and the fish is often depicted in art and literature, and it has become a popular subject for children's stories and moral lessons.
